Godolphin's Lewis Ponds Project Reveals Promising Mineralisation Extensions Through Advanced Geophysical Analysis
Downhole electromagnetic (DHEM) data reprocessing has identified six significant off-hole conductor plates outside the existing Lewis Ponds mineral resource, signalling strong expansion potential for the already substantial gold, silver and base metals deposit.
New Conductor Plates Suggest Additional Mineralised Zones
Godolphin Resources Limited (ASX: GRL) has completed comprehensive 3D reprocessing of historic DHEM data from its 100%-owned Lewis Ponds Project in NSW's Lachlan Fold Belt. The analysis revealed multiple significant conductive bodies outside the current resource envelope, providing compelling evidence for the presence of additional mineralised lenses.
The reprocessed data identified six substantial off-hole conductor plates with conductance readings ranging from 16 to 150 Siemens – consistent with the typical range (15-200 Siemens) exhibited by the known mineralisation at Lewis Ponds.
"The DHEM has been successfully used to identify massive sulphides within the current MRE area, which supports the interpretation that these additional off-hole conductors outside the MRE area could be additional mineralised lenses and represent highly prospective drill targets," said Managing Director Jeneta Owens.
The conductors are strategically positioned in three distinct zones around the existing deposit:
| Conductor Zone | Characteristics | Potential Significance |
|---|---|---|
| Northern Footwall | Two conductors (16S and 50S) located up to 200m west of Spicer's Lode | Potential new mineralised lodes within crystal tuff host rock |
| Tom's Zone Deep | Large 150S conductor (200m x 200m) below drillhole TLPD-65 | Possible deep extension of Tom's Lode beyond 900m vertical depth |
| Southern Extension | Three conductors (25S, 50S, and 100S) south of current resource | Resource extension potential with possible cross-cutting mineralised structures |
Building on an Already Substantial Resource Base
These promising geophysical results build upon Lewis Ponds' existing high-grade JORC (2012) Inferred Resource of 6.20 Mt at 2.0g/t gold, 80g/t silver, 2.7% zinc, 1.6% lead and 0.2% copper, containing:
- 398,000 oz gold
- 15.9 Moz silver
Importantly, the DHEM data within the current mineral resource area correlates strongly with known sulphide mineralisation, validating the technique's effectiveness and supporting the interpretation that the newly identified off-hole conductors may represent additional mineralised zones.
Understanding DHEM: A Powerful Tool for Subsurface Exploration
DHEM (Downhole Electromagnetic) surveying is a sophisticated geophysical technique that measures electrical conductivity from within drill holes. At Lewis Ponds, where mineralisation consists primarily of conductive sulphide minerals, DHEM is particularly effective.
When a drill hole passes near (but not directly through) a conductive body like a sulphide lens, DHEM can detect its presence as an "off-hole" conductor. The strength of conductance, measured in Siemens, helps geologists assess the potential size and sulphide content of these undrilled targets.
The significance of the Lewis Ponds DHEM results lies in the correlation between known mineralisation and conductor responses. For example, where drill hole GLPDD007 intersected 39.9m @ 3.59g/t gold equivalent at Spicer's Lode, DHEM recorded an 80 Siemens in-hole conductor response – establishing a reliable signature for identifying similar mineralisation elsewhere.
Complementary Magnetic Data Analysis Enhances Geological Understanding
Alongside the DHEM reprocessing, Godolphin has merged detailed project-scale magnetic data with regional magnetic datasets covering the entire tenement. This comprehensive magnetic mapping provides valuable insights into rock types and structural features like faults that control mineralisation.
The enhanced magnetic dataset will help Godolphin's technical team refine their geological model and better target future drilling programs aimed at resource expansion.
Upcoming Catalysts and Development Path
Godolphin is pursuing a methodical approach to resource expansion at Lewis Ponds mineralisation, with several near-term catalysts:
- A new Mineral Resource Estimate incorporating recent drilling results, due for completion in July 2025
- Deep penetrating IP survey scheduled for July 2025 to further refine drill targeting
- Integration of DHEM, IP and magnetic data to optimise future drill programs
- Ongoing metallurgical test work with samples currently at the laboratory
Investment Perspective: A Standout Polymetallic Project in Tier-1 Mining District
Lewis Ponds represents a significant polymetallic asset in one of Australia's premier mining regions. The Lachlan Fold Belt hosts numerous world-class deposits including Cadia-Ridgeway (Cu-Au), North Parkes (Cu-Au), and McPhillamys (Au).
For investors, Godolphin Resources Ltd Lewis Ponds mineralisation offers exposure to:
- A substantial existing resource with high precious metal content
- Clear resource growth potential evidenced by geophysical signatures
- A methodical exploration approach using advanced techniques
- Multiple upcoming catalysts including a new resource estimate
- 100% project ownership providing clean corporate structure
The identification of multiple off-hole conductors significantly enhances the project's prospectivity, particularly as these geophysical signatures mirror those associated with known mineralisation within the current resource.
Godolphin's technical team will integrate these DHEM results with forthcoming IP survey data to design targeted drill programs aimed at confirming these potential mineralisation extensions and ultimately expanding the resource base at Lewis Ponds.
